Hi Dmitry,

I'm glad I could help!
By the way, you can also avoid using the PMD igb driver entirely if you 
don't need it (I don't as I just care about 10Gbit interfaces, but since 
you have lots of 82576 NICs I'm not that sure); just change your compile 
configuration, either the default one or a custom one (depending on what 
you are using):

pino:~/dpdk-1.2.3r4 -> grep IGB config/defconfig_x86_64-marco-linuxapp-gcc
# Compile burst-oriented IGB PMD driver
CONFIG_RTE_LIBRTE_IGB_PMD=n
CONFIG_RTE_LIBRTE_IGB_DEBUG_INIT=n
CONFIG_RTE_LIBRTE_IGB_DEBUG_RX=n
CONFIG_RTE_LIBRTE_IGB_DEBUG_TX=n
CONFIG_RTE_LIBRTE_IGB_DEBUG_TX_FREE=n
CONFIG_RTE_LIBRTE_IGB_DEBUG_DRIVER=n


As you can see here I keep using the kernel space igb driver:

pino:~/dpdk-1.2.3r4 -> lspci -kD | grep -A 2 -i ether
